Robin Good: Sellbox is a new service which allows you to easily sell files you host on Dropbox.
"Sellbox is giving people a way to monetize the content in their Dropbox folder.
The company lets users set a price for Dropbox files, share a link to those files with their social networks, and process payments through PayPal."
"Sellbox turns Dropbox into an ecommerce platform. After connecting their Dropbox account, users select the files they want to sell, then set a file name and price. Sellers can share their files on Twitter or Facebook or via a shortened link, and buyers can pay for the files via PayPal. When a file is sold, the seller gets 91 percent of the sale and Sellbox keeps the remaining nine percent."
